a. Within the areas bounded by a line 600 mm (2
feet) outside of the trough areas for ranges,
kettles, and ovens.
b. Within the areas of potwashing and dishwashing.
In small kitchens where it may be impracticable to
subdivide areas for grouting, resin grout method
F114 or F133 may be used throughout.
For severe chemical exposure such as meat packing
plants and photo labs, resin grout method F134 will
be used throughout and a resin setting-bed will be
required. Wherever resin setting-bed is used, the
concrete slab will be steel-troweled finished to the
final slope of the finished floor. The tile shall
be set in a 3 mm (1/8 inch) thick layer of epoxy-or
furan-resin mortar. When using furan resins, the
concrete slab will be neutralized or painted in
accordance with the resin manufacturer's directions.
**************************************************************************
When resinous grout is indicated, quarry tile shall be grouted with either
furan or epoxy resin grout. Joints shall be raked and cleaned to the full
depth of the tile and neutralized when recommended by the resin
manufacturer. Epoxy resin grout shall be installed in conformance with
ANSI A108.1. Furan resin grout shall be installed in accordance with
manufacturer's instructions. Tile installed with furan resin shall be
coated with wax by the tile manufacturer. Installation of resin grout
shall be in strict accordance with manufacturer's instructions for
proportioning, mixing, installing, and curing. Recommended temperature
shall be maintained in the area and on the surface to be grouted. After
grouting, tile shall be left free of grout stain.

Ceramic Tile Grout
Ceramic Tile grout shall be prepared and installed in accordance with ANSI
A108.1.
3.4.5
Waterproofing
Shower pans are specified in Section 15400 PLUMBING, GENERAL PURPOSE.
Waterproofing under concrete fill shall conform to the requirements of
Section 07132A BITUMINOUS WATERPROOFING.

Concrete Fill
**************************************************************************
NOTE: In areas to receive conductive ceramic tile,
the first sentence will be chosen.
**************************************************************************
[Concrete fill shall be 24.1 MPa 3500 psi concrete, mixed to as dry a
consistency as practicable.] [Concrete fill shall be composed by volume of
1 part portland cement to 3 parts fine aggregate to 4 parts coarse
aggregate, and mixed with water to as dry a consistency as practicable.]
The fill shall be spread, tamped, and screeded to a true plane, and pitched
to drains or leveled as shown. Concrete fill shall be thoroughly damp
cured before application of setting-bed material . Concrete fill shall be
